The Basics

• What is Open Source Software?

4
The Basics

• What is Open Source Software?

• Literally open source disclosed to public
• Refers to intellectual property not just code
• Open does not mean free to use
• Open does not mean free to call your own
• It means relaxed or non-existent restrictions
• So who cares if its open?
• User perspective
• Developer perspective

5
The Basics

• Who is using open source software?

6
The Basics

• Who is using open source software?

• Everyone in this classroom
• Organizations and businesses of all sizes and
  types
• Schools and universities
• Governments
• Why are they using it?

7
The Basics

• Who is developing open source software?

8
The Basics

• Who is developing open source software?

• Everyday people all over the world
• Time and Passion
• People that want to invent, improve and share.
• Companies/orgs that sell services, not packaged
  SW
• Code and monetary contributions
• IBM, Google, Refractions Research, DM Solutions
• Open Non-profit and Govt organizations
• Ecotrust, Trimet
• Companies that cant afford to ignore OS
  anymore.
• Microsoft, ESRI

9
The Basics

• How is open source development different?

10
The Basics

• How is open source development different?

• Not geographically bound
• Most developers dont regularly meet face to
  face
• Rapid evolution
• Release early, release often
• Community-driven development
• Everyone can participate
• Development, testing, documentation, outreach
• Companies modify/extend and contribute back
• Accessible
• User and developer mailing lists
• chat channels
